When choosing an improper combination of
these parameters (e.g. the number of pulses
per time unit cannot be generated due to the
pulse width which is too large), one of the fol-
lowing error messages will be displayed.:

Pulse output unit:
This function is used to define the unit to be ac-
cumulated.
After selecting the function Pulse output unit,

Accumulation
of [ m3 ]
Example:
For this parameter the following units are avail-
able:

Pulse value:
This function is used to define how many pulses
will be output per accumulated unit.
After selecting the function
Pulse value
, press
the ENTER key to display the current unit:
1 pulse per
